ILLUMINATING DEVICE.

Application filed may 28, 1917. Serial No. 171,370.

One of the objects of the invention is to provide an illuminating deviceof simple and compact construction, which may be conveniently positionedwithin an obscurely lighted space to concentrate light at any particulardesired local position. A further object is to provide a device of thistype which may be placed contiguous to a door,

cover, or other closure, and having means whereby it may be operated bysaid closure, or independently thereof, at will. A further device is toprovide a portable device of the character mentioned, which isparticularly applicable for use in the cabinets of sound reproducingmachines, .to illuminate the record, the stylus, and the recordcontrolling devices, and which may be placed in position in any of thecabinets now in general use, without cutting or marring the same, oraltering the positions of any of the parts.

The invention will be hereinafter fully set forth and particularlypointed out in the claims.

In the accompanying drawing Figure 1 is a perspective view illustratingthe invention. Fig. 2 is a rear view, with the back plate or doorremoved and the battery shown in dotted lines. Fig. 3 is a transversesection on the line 3-3, Fig. 2. Fig. 4 is a similar section on the line4-4, Fig. 2. Fig. 5 is a detail view of the detachable swltch-operatingarm.

Referring to the drawing, 10 designates a casing of any desired shape,provided with a removable back plate or a door, 11, it being preferredto construct the casing of metal, although the invention is not limitedin this particular. The front wall of the casing is provided with anopening 12, and concentric therewith is a reflector 13, provided with alamp socket 14, in which is mounted an incandescent lamp 15, said sockethaving circuit with said contacts.

a base contact 16 electrically connected with one terminal of the lamp,the other terminal of the lamp being grounded through the casing.

Located at the ends of the casing are insulated supports 17, 18, thebattery 19, of the usual dry cell type, being located between saidsupports. Attached to the support 17, is an end contact plate 20,provided with an angularly disposed resilient arm 21, overhanging thebattery, and having an enlargement 22, which is pressed into contactwith the base contact 16, by the resiliency of said arm. Attached to thesupport 18, is

a spiral contact spring 23, one end of which 1 bears against the base ofthe battery '19, the

other end of the spring being bent to form an overhanging contact arm24. Attached to the top of the case 10, is a spring contact arm 25,preferably constructed of flat resilient metal, so shaped that theresiliency thereof will hold its free end upwardly in contact with thecontact arm 24. Thetop of the casing 10 is provided with a slot 27,immediately above and parallel with the contact arm 25, and working insaid slot is the shank of a slidable button 26, the lower end of saidshank being provided with a protuberance 28 frictionally engaging thecontact arm. By shifting the button 26, along said slot, the circuit isclosed or broken, as

the case may be, by movement of the free end of contact arm 25 withrespect to contact arm 24. Should it be desired to have the circuitbroken automatically by means of a door or other closure, the contact 25may be made of sufficient length to project through an opening in theback plate 11, and an angular operating arm 29, may be attached thereto,said arm having a socket to receive the end of said contact.

In operation, the battery 19 is placed between the contact spring 23 andthe contact plate 21, being held in position by the resiliency of saidspring, with its poles in The circuit may be-opened or closed, aspreviously stated, by movement of the button 26. When closed, thecircuit is from the battery 19, through contact plate 20, arm 21 andenlargement 22, to the lamp and after passing through the latter, isgrounded through the casing, passing through'contact arm 25, and contactarm 24 and spring 23,to the battery. Should the arm 29 be employed, theclosing of a door, such as the cover of the cabinet of a soundreproducing machine, will bring said door into engagement with theangular portion of said arm, causing the same to pull contact arm 25 outof engagement with the contact arm 24, so that the circuit is brokenwhile the door is closed, and illumination is not needed. As soon as thedoor is opened sufficiently, the resiliency of the contact arm willimmediately bring the same into engagement with the contact arm 24, andclose the circuit. Thus it will be seen that the circuit may be closedmanually through button 26, or automatically by means of arm 29.

Having thus explained the nature of the invention, and described anoperative manner of constructing and using the same, although Withoutattempting to set forth all of the forms in which it may be made, or allof the forms of its use, What is claimed is 1. An illuminating device ofthe character described comprising a casing, a battery supported in saidcasing in a normally horizontal position, a lamp above said battery, abattery retaining device engaging one end of'said battery and having anoverhanging contact arm, means for placing one terminal 'of said lamp incircuit With the other end of the battery, the other terminal of thelamp being grounded through the casing, and a switch arm attached to thecasing and positioned to engage said contact arm.

2. An illuminatingdevice of the character described comprising a casing,a battery supported in said casing in a normally horizontal position, alamp above said battery, a battery retaining device engaging one end ofsaid battery and having an overhanging contact arm, a flexible contactarm connecting one terminal of the lamp with the other MB end of thebattery, the other terminal of tached to the casing trically connectedthe lamp being grounded through the easing, and a switch arm attached tothe casing and positioned to engage said contact arm.

3. An illuminating device of the character described. comprising acasing, insulated supports at the ends of said casing, a flexiblecontact arm attached to one of said supports, a battery retainingdevice'attached to the other support and havingan offset overhangingportion forming a contact arm, a battery engaging said flexible contactarm and said battery retaining device, a lamp supported by said casingand having one terminal in circuit with said flexible contact arm andthe other terminal grounded through said casing, and a switch arm atandpositioned to engage said contact arm.

4:. An illuminating device of the character described comprising acasing, a lamp supported therein and having one terminal groundedthrough said casing, a battery in circuit with the other terminal ofsaid lamp, a retaining device for the battery in circuit With saidbattery, said retaining device having a terminal contact, a contact armelec- With said casing. and--10- cated contiguous to said terminalcontact, means for effecting relative movement of said contact arm andsaid terminal contact, and an offset operating arm detachably connectedWith said contact arm.

In testimony whereof I have hereunto set my hand in presence of two.subscribirig Witnesses.
